To @ZZ whom it may concern:

Beit known that I, JAMES F. DE JARNETTE, a citizen of the United States, residing at Omaha, in the county of Douglas and State 5 of Nebraska, have invented certain new and useful Improvements in Vehicle-Wheels of which the following is a specification.

My invention relates to improvements in vehicle-wheels, and articularly the wheels of io automobiles or simi ai' vehicles, and has for its object a means for spportin the .entire weight of the vehicle upon spira springs so located and confined that the resilient eI'ects of the springs bear directly uponv the tire, i5 thereby relieving lthe hub and vehicle of vibration incident to movement over uneven surfaces, also t'o provide a means for increasing or decreasin the resiliency of the springs.

lIVith these o jects in view my invention I' 2o discloses novel construction and arrangement of parts, as shown herein and more Jul trated by the drawings, wherein- Figure 1 representsa vertical side view of my newlyinvented vehicle-wheel, and in my both sides are identical. Fig. 2 is an end View of an outer-inclosing member and adjacent devices to be explained more -fullyjfin detail. y 3 is a sectional view of one of the seriesv of spiral springs and inclosing 3o members therefor; Q

I construct-and place radially between the hub and tire theseries of inolosing members 1 j and2, the inner series being mounted to have a' slight swinging movement upon the pivot- 3 5 bolt 4, and each member 1`is inclosed for a y illuspart of its length by the overlapping member 2, the latter being radially extended toa oint by means of the bolt 5 passing through the As thus constructed, the series of inclosing members I and .2 are positioned at regu'- lar radial distances apart similar to the spo es near the'tire, where a bearing is made of a wheel securedkat theirextremeouter and in a manner to prevent anysidevyise movement, but otherwise permitting a slight turning movement upon their boltsllan'd 5. l f n I vconstruct, and place within the tubular 5o walls of each of the series-of inclosing mem- ,bers the spirals ring 3 Witli'its end bearings 9 and-10, theseeari s-being integral 'With the adjacent walls of t e inclosing members,

'and'the bolt-.head 7 is provided with' a thread:

5 5 edshank 11, ttin within the grooves of the Iaperture12 othe bearing 9.,

the rings 16, and withinthe rings' 16 I construct the detaining-blocks 17, and within the s ace 18 and between the series of detaining-bllocks the inclosing member 2 is free to move', since each inclosing member is pivot ally hung at 4 and 5. A part oi the inclosing member 2 `overlaps a portion of the inclosing member 1 and is adapted 1 Rigid with the caps 14 of thevhub I'construct tlie spokes 15, which terniinatefwitlun' 6 5 to readily revolve thereon by turnin@r itwith-tlie hand, and itis evident that revolutions in one direction of the inclosing and .thereby increase'- the tension of spring,

' said spring, and revolutions in the opposite direction will lengthen the space and will decrease the tension 'of the spring, as isl obvious.

In operation, the wheels being mounted upon a vehicle, the entire weight is directed u on the lower series of springs, and as the member 2 will tend to shorten the lengthwise space occupied by the spiral w eel revolves tlie entire' series ofl spiral I springs are 'called into use in alternation. v In starting or stop ing the vehicle there will be a movement'o the inclosing members toconstruction of hese with the .hub is rigid the inclosing members are held to a substantially'true radial position upon the hub center, and the spiral ward the detaining-blocks 17 but sincevthe blocks and their rings s rin s'receive any and all vibrations irom t e tire caused by moving over rough pave- 4mentsor uneven surfaces.

Various inodiications of minor details my construction may be made without departing, from the invention, its scope being determined by its claims. i

What I claim as m invention is i 1. A vehicle-wliee ,i in combination, comprising a hub; coiled'spiingsga tire; a series of spokes rigidly mounted upon the hub and eX- tending therefrom apart of thev radial dis,-

tance from the hub to the tire g'annular rims said annular'rims being mounted rigid upon said series of rigidly-mounted spokes; Vresiliently-formed spokes ;V said resiliently-fornied spokes being eachcomposed of two tube por*- IOO tions having suitable spring-bearing ends, said tube portions of each spoke being of different diameters and of a length les's than the radial distance Jf'ro`mtlie-hub to the tire theeiidof one tube portion being pivo'tallymounted upon the hub, he end of the other tube portion o eachl tubular spol're inlosing the opposite endand part ofthe body of the other tube por- IIO tion and forming within saidgtube portions a radially'- extending chamber; one of said coiled springs being seated within each of chambers and extending lengthwise therein between said spring-bearing ends of said tube portions; said resiliently-formed spokes being 'disposed between and closely adjacent to said annular rims.

2. A vehicle-Wheel; in combination; coinprising a hub a tire spiral springs resilientlyformedy Ispokes; bearing-heads having threadand-groove stems; each of said resilieiitlyior'iied spokes consisting of two radially-errteiiding tube portions of differing diameters and each being of a less length than thexradial distance from the hub to the tire; a part of one tube portion being inclosed by a part voi the other tube portion; one 01"' said tubeportions having a closure at one end ;vsaid closure Ahaving a thread-and-groove aperture therein adapted to receive the stein of said bearing-head; said bearing-head being ivotally mounted upon said tire; the other tube portion having an endl closure and mounted upon the hub at the end having said end closure; a longitudinal chamber formed within said tube portions and between-said closures,

'and a spring seated therein.

3J A vehicle-Wheel, in combination; coniprising a hub; a tire; spiral springs; a series of spokes ri idly mounted upon the hub and extending t erefrom apart of' the radial distance from the hub to the tire; circular rim portions; said circular rim portions being mounted rigid upon said series of ri idly-mounted spokes;'resiliently-formed spo es; said resiliently-formed spokes being each composed of two tube portions having suitable springbearing ends, said tube portions of each spoke vbeing of different diameters and of a length less than the radial distance from the hub to lthe tire; the end of one tube portion beinor pivotally mounted upon the hub; the end b other tube portion being pivotally mounted upon the tire; the opposite end of one tube por- .4s inclosing the o tion o earch of said resiliently-formed posite end and a part of the er tube portion, and forming said tube portions a radially-extending spokes body of the et chamber one of said spiral springs being seatof the ed Within each of said chambers and extend- 'ing lengthwise therein between said springbearing ends of said tube portions; said resiliently-formed spokes being disposed between 'and closely adjacent to said circular riin portions; and means to increase ror decrease the resiliency oie said springs at will.

4. A vehicle-wheel, in combination; cloni-l prising a hub a tire; spiral springs resilientlyformedspokes; bearing-heads having threadandgroove stems; circular rim portions; stop-blocks ,'l a series of spokes rigidly mounted upon the hub and extending therefrom a part of the radial distance from the liub to thetire; said circular rims being mounted rigidly upon said series of rigidly-mounted spokes one upon either side of said spokes and at equal distances Jfrom said hub; each of said resilicntly-formed spokes consisting of two rad ially-eXtend ing tube portions of diftering diameters and each being of ailess length than tlie radial-distance from thehub to the tire a part of one tube portion being inclosed by a part of the other tube portion; one of said tube portions having a elo'sre at one end sai'dclosure having a thriit-n/nd-groove aperture therein ad apted to receive the stein. of said bearing-head ;said bearing-head I'seing pivotally mounted upon said .,tiie; the other tube portion havingan eiid closure; a longitudinal chamber formed within said tube portions and between said closures, and one of' said spiral springs seated therein; said stop-l blocks being mounted rigidly between the transverse walls of the circular rim portions rigidly with said series of rigidly-mounted spokes,A said resiliently-mounted spokes be-` ing adapted to havea radial movement upon their pivotal bearings between said circular rim' portions andbetween said sto -blocks and nieaiis to increase or decrease t e resiliency of said springs at will, substantially as described. i

In testimony whereof I'have affixed my sigl nature in presenceof two witnesses.
